Fluctuation-dissipation: Response theory in statistical physics
Cultural route to the emergence of linguistic categories
TLDR
This work addresses the question of whether categories simply mirror an underlying structure of nature or instead come from the complex interactions of human beings among themselves and with the environment by modeling a population of individuals who co-evolve their own system of symbols and meanings by playing elementary language games.
Temperature in and out of equilibrium: A review of concepts, tools and attempts
Statistical physics of language dynamics
TLDR
Some of the progress made in the past few years are reviewed and potential future directions of research in this area are highlighted, as examples corresponding to the early stages of a language.
Exploring the Roles of Complex Networks in Linguistic Categorization
TLDR
A general framework to systematically explore the effect of social structure on language evolution is illustrated and the isolating and collective effects of some structural features, including average degree, shortcuts, and level of centrality, on the categorization process are examined.
Kinetic model for the finite-time thermodynamics of small heat engines.
TLDR
A three-variables Langevin model is developed in which the piston's position and velocity are linearly coupled together with the internal energy of the gas, which reproduces many of the system's features, such as the inversion of the work's sign, the efficiency at maximum power, and the approximate shape of the fluctuations.
Nonequilibrium and information: the role of cross correlations.
We discuss the relevance of information contained in cross correlations among different degrees of freedom, which is crucial in nonequilibrium systems. In particular we consider a stochastic system…
Clausius Relation for Active Particles: What Can We Learn from Fluctuations
TLDR
Three different recipes to define heat and entropy production have been proposed for the same model where the role of self-propulsion is played by a Gaussian coloured noise and the relation between such proposals and their physical meaning is compared and discussed.
Irreversible effects of memory
The steady state of a Langevin equation with short-ranged memory and coloured noise is analyzed. When the fluctuation-dissipation theorem of second kind is not satisfied, the dynamics is…
Entropy production and coarse graining in Markov processes
TLDR
The results provide strong evidence that entropy production is not directly affected by a coarse-graining procedure which decimates fast states with respect to a given time threshold, provided that it does not entirely remove loops carrying a net probability current.
